Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31228, here are decompositions:

5 + 31223 = 31228
47 + 31181 = 31228
89 + 31139 = 31228
107 + 31121 = 31228
137 + 31091 = 31228
149 + 31079 = 31228
251 + 30977 = 31228
257 + 30971 = 31228

Showing the first eight; more decompositions exist.
